IT Infrastructure

Most IT managers are aware of the important role that IT plays in business today. However,
some individuals in the business community do not always understand the need for IT
involvement in day-to-day operations. What are the primary functions of IT in business today
and how would you explain these roles to a business executive who feels IT is just a support
function?
One of the most important roles of IT managers is to make sure that communication is available

More businesses are using just-in-time purchases to reduce warehousing costs and ensure an upto-date inventory. How does the use of the extranet help with this process? What network issues
must be reviewed to make it a success for both the business and the vendor?

Most networks today are based on Ethernet technology. Part of this is due to the ease of
installation and reduced costs. However, there are other network technologies still in use. What
are they and where and how are they used most prevalently? How would you as the IT manager
convince executive management that they should be upgraded?
Give an example from personal experience, research, or through something you read of an
Intranet application that improved the way something was done in a company. How did the
application improve a particular process? Can you see ways the application can be improved to
improve the process even more?

Chtioui article, the purpose of the ERP software is outlined. What are these purposes and why is
standardization necessary? What are the positive effects on work performance because of the
changes that take place with ERP use?
Application software is essential to make workers more efficient and maintain company
information. However, determining the best software to use is often difficult. Your course
readings provide an IT Performance Model to determine how software contributes to the
company. What are the individual areas in this model and how would they be used to determine
the type of software needed for an organization? Are there any areas that were left out and how
would they be incorporated in this model?
Many businesses are partnering to take full benefit of global economies. Global use of
networking technology requires a collaborative effort to be successful. What are the facets of
partner relationship management and what network considerations must be reviewed to ensure
success? Review the course reading for examples of use and explain how these ventures were
successful in their efforts. Would these uses also be beneficial to your businesses and what
modifications would be needed for their use?
Many companies are moving to the use of mobile computing. Employees use smart phones
instead of a laptop to reduce the amount of equipment purchases and to maintain 24/7 contact.

How is this affecting network usage for the company? What are some important considerations
when moving to this technology?

to expand the companyâ&#x20AC;&#x2122;s bottom line?

the majority of these uses were for customer surveys and marketing. What effect does this have
on the current network environment of the company? With the Web 2.0 revolution, what are
